Rejecting ! Block has invalid fork version actual 4 expected 3

Hi,

I have downloaded the daemon from github and have been syncing for a few days from a fresh install, but now I am getting this :

I have found this Rejecting ! Block has invalid fork version actual 3 expected 2 but it is a rather old topic and does not help.

Please use latest release of DERO daemon, miners etc. https://github.com/deroproject/derosuite/releases
Wait for full sync before mining.
ATM blockchain takes ~ a week to fully sync from zero.
If you require recent blockchain snapshot for faster sync pls ask here.

Run your DERO daemon with following option:
./derod-linux-amd6 --add-priority-node=190.2.135.218:20202 --add-priority-node=212.8.242.60:20202 --add-priority-node=212.8.250.158:20202

I have installed latest version (2.2.1-0) and syncing resumed from where I was :slight_smile: :ok_hand:
Thanks!

I thought I had the latest version already,
but I got my daemon from Install a full DERO node with stats, the easy way. | by Joshy | DERO | Medium which is outdated (and perhaps not official).

Note : syncing has resumed with just the simple command
./derod-linux-amd64
without argument.

Wait for daemon to full sync. It may take a week and ~40GB space.
